The three giants tombs were found on the southwest corner of a 105-foot [32-meter] mud-brick pyramid at Dos Cabezas, an ancient Moche settlement along the Jequetepeque River. Unlike the pyramids of Egypt, which were built as tombs, the Dos Cabezas pyramid was more like a high-rise ceremonial complex. Built in stages, the pyramids grew as rooms, patios, and walkways were filled in and became part of the solid structure. Workers sealed the three tombs with mud bricks and kept on building.
